The purpose of this study was to examine that multiple mediating effects of self-determination and self-efficacy in the relationship between the parental control and career maturity. In the study, 747 university students in Daegu, Busan and Seoul area were surveyed on their perceived level of parental control, career maturity, self-determination and self-efficacy. Data were analyzed using descriptive statistics, one-way ANOVA, and Pearson correlation analysis with SPSS 25.0 program, Hayes'Process Macro program and bootstrapping. The major results of this study were as follows; First, there were significant differences in college student's career maturity by grade, major, experience in career-related services and part-time job experience period. Second, there were significant correlations between parental control(behavioral control and psychological control), career maturity, self-determination and self-efficacy. Third, self-determination and Self-efficacy had multiple mediating effects in the relationship between parental control and career maturity. In conclusion, this study found multiple mediating effects of self-determination and self-efficacy in the relationship between parental control(behavioral control and psychological control) and career maturity. It was also found that parental behavioral control had a positive effect on career maturity by increasing self-determination and self-efficacy while parental psychological control had a negative effect on career maturity by decreasing self-determination and self-efficacy.

The Randomized Control Trial (RCT) is the most well-established and widely used statistical methodology in clinical research; however, applying thorough RCT to cancer patients presents challenges such as ethical concerns, high costs, short clinical periods, and limitations in collecting various side effects. To address this issue, the propensity score matching method, which takes advantage of the benefits of observational research while compensating for the drawbacks of randomized control trials, is used in a variety of fields. In recent years, 28 studies on the effectiveness of Korean medicine on tumors have been conducted abroad using the Propensity Score Matching Method, but none have been conducted in Korea. The majority of studies have focused on liver cancer, colon cancer, lung cancer, and stomach cancer, with endpoints such as survival time, incidence rate, quality of life, and treatment outcomes revealing statistical differences in how Korean medicine intervention affects treatment outcomes. As a result, well-established studies using the propensity matching score methodology should be useful in evaluating the impact of Korean medicine in oncology treatments.

We investigated the effect of Takju lees extract on blood glucose levels in the db/db mice (a murine model of type 2 diabetes mellitus). We fed 40 male db/db mice a control diet (G0, AIN93G) and experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extract for 4 weeks. We found no difference in food intake and body weight gain among the animal groups. In the G1 and G2 groups, plasma glucose levels decreased significantly between Days 10 and 21 compared with the G0 group. However, we found no difference in plasma glucose levels between groups G4 and G0. The change in insulin concentrations was not significant among these animal groups, and we found no significant difference in glucose transporter 4 (GLUT4) expression in the soleus muscle. These results suggest that the Takju lees extract has a beneficial effect in animals with type 2 diabetes.

Purpose: This study aimed to examine the relationships between positive nursing organizational culture, organizational communication satisfaction, and the level of work engagement among nurses working in tertiary hospitals, as well as to identify influencing factors on work engagement. Methods: This study used a descriptive research design. Data were collected from 184 general nurses working in four tertiary hospitals in Seoul using self-report questionnaires from March 13 to 30, 2023. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Scheffé test, Pearson correlation, and hierarchical regression. Results: In the hierarchical regression analysis, the variables that significantly influenced work engagement in Model 1 were marital status (β=.26, p=.002), graduate or higher degree (β=.41, p<.001), more than 1 year and less than 3 years (β=.18, p=.030) and 3 years or more but less than 5 years of clinical experience in present hospital (β=.17, p=.023), and satisfaction (β=.27, p=.002) and moderate satisfaction with pay (β=.18, p=.033). In model 2, adding the subdomains of positive nursing organizational culture and organizational communication satisfaction to the Model 1, the variables that had a significant effect on work engagement were trust-based organizational relationships (β=.50, p<.001) and organizational communication satisfaction (β=.25, p=.005). Conclusion: The results suggest that education level, clinical experience, and satisfaction with pay should be considered to improve nurses' work engagement. In addition, it was identified that organizational relationship based on trust and organizational communication satisfaction are the main influencing factors for improving work engagement.

This study examines the concepts and characteristics of Interculturalism and extracts artistic expressions of intercultural characteristics shown in Nouvelle Danse and Non-Danse, which were the birthplace of the contemporary dance flow in Europe. The discussion and composition of these dances will be analyzed from an intercultural perspective by selecting three works by each choreographer representing Nouvelle Danse and Non- Danse. In doing so, we would like to examine what creative acceptance was achieved based on the values and understanding in the clash and encounter between different cultures in art. Dance and interculturalism emphasize exchanges and encounters between one's own culture and other cultures. In addition, it has the potential to contribute to dance studies through the humanistic perspective of dance, as it also contains issues about diversity and identity due to exchange between cultures at the center of globalization. Therefore, the purpose of the study is to read the artistic expressions of choreographers in Nouvelle d'Anse and Non-d'Anse through intercultural understanding with an in-depth understanding and to interpret them by adding multi-layered time to the study.

Background/Aims: To determine whether metformin, which is considered a host-directed therapy for tuberculosis (TB), is effective in improving the prognosis of patients with TB and diabetes mellitus (DM), who have higher mortality than those without DM. Methods: This cohort study included patients who were registered as having TB in the National Tuberculosis Surveillance System. The medical and death records of matched patients were obtained from the National Health Information Database and Statistics Korea, respectively, and data from 2011 to 2017 were collected retrospectively. We classified patients according to metformin use among participants who used diabetes drugs for more than 28 days. The primary outcome was all-cause mortality during TB treatment. Double propensity score adjustment was applied to reduce the effects of confounding and multivariable Cox proportional hazard models were used to estimate adjusted hazard ratio (aHR) with 95% confidence interval (CI). Results: The all-cause mortality rate during TB treatment was lower (9.5% vs. 12.4%, p < 0.01) in the metformin user group. The hazard of death due to all causes after double propensity score adjustment was also lower in the metformin user group (aHR 0.76, 95% CI 0.67-0.86, p < 0.01). There was no significant difference in mortality between metformin users and non-users for TB-related deaths (p = 0.22); however, there was a significant difference in the non-TB-related deaths (p < 0.01). Conclusions: Metformin use in patients with TB-DM co-prevalence is associated with reduced all-cause mortality, suggesting the potential for metformin adjuvant therapy in these patients.

Purpose: The purpose of this study was to conduct a pre-conception care program for women of childbearing age with inflammatory bowel disease (IBD) in Korea and verify its effects on self-efficacy for IBD management, IBD-related pregnancy knowledge, and IBD-related pregnancy anxiety. It also aimed to explore the changes in participants through the program. Methods: A convergent mixed-methods study design was adopted. In the quantitative phase, 35 women (17 and 18 in the intervention and control group, respectively) participated. The intervention group attended a program that included small-group sessions and individual tele-coaching. To confirm the effects, data were collected before and one and four weeks after the intervention. In the qualitative stage, focus group interviews and tele-coaching were conducted with the intervention group. Results: After the program ended, significant differences were observed over time between the intervention and control groups for self-efficacy for IBD management (Wald χ² = 4.41, p = .036), IBD-related pregnancy knowledge (Wald χ² = 13.80, p < .001) and IBD-related pregnancy anxiety (Wald χ² = 8.61, p = .003). Qualitative data analysis revealed the following themes: (1) improving confidence in IBD management and awareness for planned pregnancy; (2) improving IBD awareness related to pregnancy and childbirth; and (3) relieving anxiety about and actively facing pregnancy. Conclusion: This study is meaningful in that, to the best of our knowledge, it is the first to develop a pre-conception care program for women diagnosed with IBD and confirm its effectiveness. Furthermore, this program is expected to be suitable for patient counseling and education in clinical practice.

The objective of this study was to examine the distinctiveness and generality of landforms of the Korean peninsula, and further discover geomorphological principle that can be applied to land and environmental management in Korea. The research targeted East Asia and Korea, with terrain analysis conducted at a continental scale, national scale, and regional scale sequentially. East Asia displays complicated characteristics and evolutionary history of geotectonics, but exhibits distinct northeast-southwest geomorphological structure and connectivity at the continental level. While the Korean peninsula follows this pattern on a continental scale, it also features NNW-SSE direction (Nangrim and Taebaek Mountains) geomorphological connectivity that intersects at a right angle. From a national perspective, the Korean peninsula hosts the most diverse geomorphological features within East Asia. It does not have a high average altitude, but has relatively high slope angle and intricate topographical distribution in comparison to neighboring areas. While the mountains and plains of the Korean peninsula display a smooth connection, geomorphologically similar areas such as Shikhote-Alin, Huanan in China, and Japan have clear characteristics that divide the mountains and plains. Despite the distinctiveness and diversity that appear in East Asian topography on the regional scale, the connectivity that links the top of mountain (hill) to stream is identical among all areas as a general rule. It is collectively considering the connectivity and the geomorphological and ecological processes that arise within this connectivity that will serve as the focal point for sustainable landscape management.

Artificial Asian dust was treated in this study to compare and determine its effect on growth, photosynthesis, respiration and stomata of 5 species trees. Sophora japonica's growth and respiration using artificial Asian dust treatment which is 10 times of average contents of Asian dust: $5,000{\mu}g{\cdot}m^{-2}$ decreases after 3 weeks while no significant difference in other species. The maximum photosynthesis of Sophora japonica and Betula pendula decreased significantly after 3 weeks and 6 weeks, respectively, using artificial Asian dust treatment which is average contents of Asian dust: $500{\mu}g{\cdot}m^{-2}$. At $5,000{\mu}g{\cdot}m^{-2}$ treatment, photosynthesis of both species decreased just after treatment of artificial Asian dust. Quercus acutissima, Quercus mongolica and Acer triflorum have no significant differences. Dust was found inside the Sophora japonica's stomatas under heavy dust treatment when viewed under the light electron microscope. By scanning electron microscopy, the higher rate of stomatal opening of Sophora japonica and Betula pendula was recognized and the size of both stomatas was bigger than other species. This result means that Asian dust has an influence in decreasing the photosynthesis, respiration and growth of some species especially if the stomatas are large.
